Pain words stand out more for those experiencing it

Posted: 03 Oct 2014 10:57 AM PDT

Ache, agony, distress and pain draw more attention than non-pain related words when it comes to people who suffer from chronic pain, a research using state-of-the-art eye-tracking technology has found.

Untangling how cables coil

Posted: 03 Oct 2014 10:57 AM PDT

Engineers together with computer scientists have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics technology used to animate hair in movies, and theoretical analyses.

Crumpled graphene could power future stretchable electronics

Posted: 03 Oct 2014 10:57 AM PDT

When someone crumples a sheet of paper, that usually means it's about to be thrown away. But researchers have now found that crumpling a piece of graphene "paper" -- a material formed by bonding together layers of the two-dimensional form of carbon -- can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.

Healthy knowledge management and social networking

Social network analysis could improve knowledge sharing in the health-care sector, according to new research.

Fast, cheap nanomanufacturing: Tiny conical tips fabricate nanoscale devices cheaply

Posted: 03 Oct 2014 10:54 AM PDT

Scientists have developed dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and "smart" textiles; or propulsion systems for fist-sized "nanosatellites."

Global database: Cattle genome cracked in detail

Posted: 03 Oct 2014 06:22 AM PDT

An international consortium of scientists has increased the detailed knowledge of the variation in the cattle genome by several orders of magnitude by creating a global database. The first generation of the new data resource, which will be open access, forms an essential tool for scientists working with cattle genetics and livestock history.

New method for detecting water on Mars

Posted: 03 Oct 2014 03:45 AM PDT

An undergraduate student has helped develop a new method for detecting water on Mars. Water is a key indicator for the potential of microbial life on the red planet. While reseachers didn't see evidence of it from two sites they studied, their method could look for water elsewhere.

Scientists design an imaging system capable of obtaining twelve times more information than the human eye

Posted: 03 Oct 2014 03:44 AM PDT

Researchers have designed a new imaging system capable of obtaining up to twelve times more color information than the human eye and conventional cameras, which implies a total of 36 color channels. This important scientific development will facilitate the easy capture of multispectral images in real time, and in the not too distant future it could also be used to develop new assisted vehicle driving systems, identify counterfeit bills and documents or obtain medical images much more accurate than current ones, among many other applications.

New materials for better, stronger and cheaper dental implants

Posted: 03 Oct 2014 03:44 AM PDT

A ceramic polymer blend has been developed by researchers to reduce costs of dental implants. "By optimizing the geometry and consistency of the implants we can ensure that they remain in place longer, but with a lower cost than the titanium implant," said the project collaborator in charge of industrial design.

Batteries included: A solar cell that stores its own power

Posted: 03 Oct 2014 03:43 AM PDT

Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device is both: the world's first solar battery. Scientists have succeeding in combining a battery and a solar cell into one hybrid device.

Toxicity test technology hits the market

Posted: 02 Oct 2014 07:11 PM PDT

A technique for high throughput screening of substances that could cause DNA damage has been developed by scientists. The technology allows for testing of drugs and cosmetics that could pose a risk to human health, and assesses damage done to DNA, while reducing reliance on animal testing, researchers say.

From surgery to recovery: Athletes and ACLs

Posted: 02 Oct 2014 03:39 PM PDT

National Hockey League players have the best chance to return to their sport after an ACL tear, and snowboarders have the lowest rate of returning to their sport, according to a series of papers.

Physicist turns smartphones into pocket cosmic ray detectors

Posted: 02 Oct 2014 01:26 PM PDT

A new smartphone app can essentially turn Android phones into pocket cosmic ray detectors. The app, DECO, uses the phone's camera to capture energetic subatomic light particles and log data.

Software for Google glass that provides captions for hard-of-hearing users

Posted: 02 Oct 2014 01:26 PM PDT

Speech-to-text software for Google Glass has been created that helps hard-of-hearing users with everyday conversations. A hard-of-hearing person wears Glass while a second person speaks directly into a smartphone. The speech is converted to text, sent to Glass and displayed on its heads-up display.

Falling asleep: Revealing the point of transition

Posted: 02 Oct 2014 11:18 AM PDT

How can we tell when someone has fallen asleep? To answer this question, scientists have developed a new statistical method and behavioral task to track the dynamic process of falling asleep.

Fine tuning nanoparticles for the medical industry

Posted: 02 Oct 2014 05:41 AM PDT

Nanoparticles have the potential to revolutionize the medical industry, but they must possess a few critical properties. First, they need to target a specific region, so that they do not scatter throughout the body. They also require some sort of sensing method, so that doctors and researchers can track the particles. Finally, they need to perform their function at the right moment, ideally in response to a stimulus. Scientists are trying to develop new particles with unprecedented properties that still meet these requirements.

New nanomaterial introduced into electrical machines

Posted: 02 Oct 2014 05:41 AM PDT

Scientists have now constructed the world's first prototype electrical motor using carbon nanotube yarn in the motor windings. The new technology may significantly enhance the performance.

Ultrafast remote switching of light emission

Posted: 30 Sep 2014 01:07 PM PDT

Researchers can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
